STR9 RTC Interrupt

I was following the program. but it doesn't work.

Can you help Are You? Where I'm wrong.

/*
WakeUp Interrupt Unit(WIU) -> Vectored Interrupt Controllers(VIC) -> IRQ Handler
or
Vectored Interrupt Controllers(VIC) -> IRQ Handler
@ WIU_Line != VIC_Line.
ex)
VIC : WIU_ITLine - WIU : WIU_Line 0~31
VIC : EXTIT0_ITLine - WIU : WIU_Line 0~7 = USB, RTC, Port 3.[7:2]
VIC : EXTIT2_ITLine - WIU : WIU_Line 16~23 = Port 6.[7:0] interrupts
VIC : TIM0_ITLine - no use WIU

WIU_ClearITPendingBit(WIU_Line1); } RTC_PeriodicIntConfig (RTC_Per_128Hz);
}

ps. i worked the program use task.

void vRTCTasks( unsigned portBASE_TYPE uxPriority)
{ RTC_Init(); xTaskCreate( vRTCtesttask, ( signed char * ) "RTC_Test", configMINIMAL_STACK_SIZE +900, NULL, uxPriority, ( xTaskHandle * ) NULL );
} /*-----------------------------------------------------------*/
static portTASK_FUNCTION( vRTCtesttask, pvParameters )
{ int ncnt=0; ( void ) pvParameters;

while(1) { if(ncnt>250) { RTC_GetDate(BINARY, &d_rtc); RTC_GetTime(BINARY, &t_rtc); //Ts_a=t_rtc.seconds; // Get the date again if the current time is 00:00:00 (Midnight)

if ((t_rtc.hours == 0) && (t_rtc.minutes == 0) && (t_rtc.seconds == 0)) RTC_GetDate(BINARY, &d_rtc); //if(Ts_b!=Ts_a) //{ xPrintf(" %04d %02d %02d %02d:%02d:%02d \r\n", d_rtc.century*100 + d_rtc.year, d_rtc.month, d_rtc.day, t_rtc.hours, t_rtc.minutes, t_rtc.seconds ); //} //Ts_b=Ts_a; ncnt=0; } vTaskDelay(2); ncnt++; }
